“…The results demonstrated that the proposed approach has a high sensitivity and good repeatability, and thus, it is reliable for the analysis of parabens in environmental samples. A comparison of the method with other previously reported methods is listed in Supporting information Table S3 [14,23,24]. These results showed that the developed SPME-UHPLC-MS/MS method has good preconcentration capability and excellent sensitivity.…”

“…Insofar as the analytical method is concerned, several combinatorial methods, including gas chromatography-mass spectrometry [20][21][22][23], liquid chromatography-ultraviolet spectroscopy [24][25][26][27], and liquid chromatography-mass spectrometry [28][29][30][31][32], have been applied to detect parabens. At present, ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) has become one of the most powerful analytical methods for the detection of trace compounds owing to its excellent resolution, which facilitates the identification of trace parabens in environmental samples.…”

Widespread use of parabens in consumer products has resulted in their ubiquitous existence in the environment including sewage, soil, and sewage sludge. Their potential for human health hazards has, therefore, raised significant public concerns. In this work, an effective in-tube solid-phase microextraction device based on a poly(4-vinylphenylboronic acid-co-ethyleneglycol dimethacrylate) was combined with analysis with ultra-high-performance liquid chromatography-tandem mass spectrometry for detecting parabens in sewage and soil samples, with the limits of detection ranged between 0.64 and 1.4 ng/L.Trace parabens in sewage and soil samples were determined, with amounts of four parabens in the range 0.0141-3.78 ng/g, whereas benzylparaben was not detected. Satisfactory recoveries were observed for the five parabens (86.4-113%), with relative standard deviations (n = 5) ranging between 2.1 and 6.0%. The results indicated that the developed method is prospective to expand in environmental monitoring.

“…Nowadays, the antimicrobial activity of parabens is more and more answered, in particular methyl, ethyl, propyl, butyl and benzyl paraben (group of homologous p-hydroxy benzoates) are used widely as preservatives (Zhao et al, 2014;Valle-Sistac et al, 2016;Chen et al, 2018;Nowak et al, 2018;Berger et al, 2018) in foods, beverages, toiletries, pharmaceutical and specially in cosmetic products because of their biodegradability, good stability, efficiency in wider pH range and other properties such as low cost and no color (Gholivand et al, 2014;Michalkiewicz et al, 2016;Yazdi et al, 2018).…”

Purpose The purpose of this paper is to study the immobilization of porcine pancreatic lipase (PPL), in an organic matrix by a covalent cross-linking method to sense propylparaben (PP) present in aqueous solution. Design/methodology/approach PPL immobilization was performed by the covalent cross-linking method, using bovine serum albumin (BSA) in the presence of saturated glutaraldehyde vapor (GA). The preparation of the enzymatic membrane involves the incorporation of porcine pancreatic lipase (PPL), bovine serum albumin (BSA) and glycerol into a phosphate buffer solution (PBS). Characterization of this sensor was performed by impedance spectroscopy (EIS) and scanning electron microscope (SEM). The effect of experimental conditions such as PPL activity, potential, scan rate, PP concentration, pH and presence of interfering elements were studied by cyclic voltammetry. Findings Under the optimal experimental conditions, a number of significant factors were optimized. The method exhibited good linearity in the range of 10–14 to 10–9 mol/L with a good correlation coefficient of 0.957, detection limit (LOD) of 3.66 × 10–15 mol/L and high sensitivity of 1.086 mA mol−1L. The authors also obtained a very good coverage rate of the surface equal to 91.44%, and hydrolytic activity of lipase is evaluated to 26.64 mmol min−1. The stability and the interference were also evaluated. The equivalent circuit used to explain the electrochemical behavior of modified electrode is a Randle circuit. Practical implications The main application of biosensors is the detection of biomolecules that are either indicators of a disease. For example, electrochemical biosensing techniques can be used as clinical tools to detect breast tumors, because these compounds (PP) were found in breast tumors. Originality/value The result registered in this paper indicates that the developed sensor is an efficient, fast, simple and inexpensive analytical tool that can be used for the analysis of water containing PP.

The whole grain intake is closely associated with human health. In this work, three‐phase dynamic hollow‐fiber liquid‐phase microextraction reinforced with 0.10 mg/mL 30 nm zeolitic imidazolate framework‐8 nanoparticles was introduced for purification and enrichment of free urinary metabolite biomarkers of whole grain intake. Eight milliliters of HCl (pH 3.00) and 8 μL of 300 mM NaOH solutions were used as the donor and acceptor phases, respectively. The temperature and stirring rate were kept at 25℃ and 500 rpm, and the extraction time was 40 min. The extraction process required no further desorption, and the resultant extract was directly used for electrophoretic analysis without derivatization. Based on the synergistic effect of hollow‐fiber liquid‐phase microextraction and the electrophoretic stacking, the enrichment factors of 3,5‐dihydroxybenzoic acid and 3‐(3,5‐dihydroxyphenyl)‐1‐propionic acid reached 1018–1034 times, and their limits of detection achieved 0.33–0.67 ng/mL (S/N = 3) in urine matrix. The developed method has been successfully used for urine analysis, and the sample recovery data were in the range of 97.0–103.5%. This developed method provided an attractive alternative for the determination of urinary metabolite biomarkers of whole grain intake due to its sensitive, fast, low‐cost, and environmental‐friendly features.
